Abstract

La présente invention concerne un conteneur de transport empilable intermodal qui est utilisé pour stocker et transporter des matériaux radioactifs. Le conteneur comporte une cloison intérieure divisant le conteneur en une zone de stockage radioactif et une zone d'équipement isolée de façon radioactive de la zone de stockage. Une porte d'accès permet à une personne d'entrer dans la zone d'équipement depuis l'extérieur du conteneur, et sans ouvrir la zone de stockage. La zone d'équipement contient un équipement de sécurité électronique et de surveillance de rayonnement, qui est configuré pour détecter un accès à la zone de stockage et pour détecter la radioactivité ambiante dans la zone de stockage. Un matériau de blindage contre la radioactivité recouvre la surface de la cloison intérieure. Un équipement de communication transmet l'état de rayonnement et l'accès au conteneur.
